Multi-Encoding Auto-Detector
Paste encoded text to automatically identify the encoding scheme and decode it. Supports Base64, hexadecimal, binary, Morse code, ROT13, URL encoding and HTML entities. All processing is local — no server involved.
Supported encodings
This tool attempts to decode text using common encoding schemes used in CTFs, obfuscation, and steganography:
Binary — 8-bit groups separated by spaces.
Base64 — A-Za-z0-9+/ characters, padded with =.
Hexadecimal — pairs of hex digits (00–FF).
Morse Code — dots, dashes, slashes for word breaks.
URL Encoding — %XX percent-encoded sequences.
HTML Entities — & < &#NNN; patterns.
ROT13 — Caesar cipher rotated 13 positions.
All decoding happens locally in your browser. No data is sent anywhere. -"
